a shake of the head

there's little profit in drawing the map
those who have knowledge don't forget the way
and only fools won't learn it in a day
you stand aside and simply praise and clap
let those who understand now bear the cap
and leave such matters to those who essay
not to attempt the difficult in play
and who won't fall into the first plain trap
wisdom's the course that only few can find
for older heads have got the sense to know
what youth discovers without any plan
that no door opens merely to the mind
and not all force is there simply for show
what's in the rear counts more than in the van
